JEE MAIN - Chemistry (2021 - 31st August Morning Shift - No. 11)
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R) :
Assertion (A) : A simple distillation can be used to separate a mixture of propanol and propanone.
Reason (R) : Two liquids with a difference of more than 20$$^\circ$$ in their boiling points can be separated by simple distillations.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion (A) : A simple distillation can be used to separate a mixture of propanol and propanone.
Reason (R) : Two liquids with a difference of more than 20$$^\circ$$ in their boiling points can be separated by simple distillations.
In the light of the above statements, choose the most appropriate answer from the options given below :
(A) is false but (R) is true.
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
(A) is true but (R) is false
Both (A) and (R) are correct and (R) is the correct explanation of (A).
Explanation
Simple distillation can be used to separate a
mixture of propanol and propanone.
• Two liquid with difference in B.P. around 20°C can be separated by simple distillation.
• B.P. of propanol is 370 K.
B.P. of acetone is 329 K.
Both assertion & reason are correct & (R) is the correct explanation of (A).
• Two liquid with difference in B.P. around 20°C can be separated by simple distillation.
• B.P. of propanol is 370 K.
